Start Vold on early-fs

We need vold on early-fs so we can handle userdata checkpointing.
Without this, devices will take an extra minute or two as checkpointing
related vdc calls attempt to reach vold before it is available.

Bug: 134114000
Test: Boot, see vold has started before vdc checkpointing tries to call
out to vold.

Remove ACgroupController_getFlags to fix API breakage

Since ACgroupController_getFlags was introduced after LLNDK freeze it
causes media crashes due to missing symbol. Remove the new function and
re-implement cgroup controller detection to not require flags field but
instead check for its existence on the first access.

Support importing property file with expanded name

This change is to support importing property file with its path
variations.

By substitute its filename with another, it can be used to handle
runtime varying filename within single binary.

Here's an example of usage in property defined file.
import /odm/build_${ro.boot.product.hardware.sku}.prop

Bug: 132592551
Test: boot a device and checks above example import statement in
"/odm/build.prop" loading expanded filename correctly

race condition in libprocessgroup

race condition in libprocessgroup

while enable fdsan (file descriptor sanitizer),
fdsan report use-after-close error after boot complete (sedom).

Because, in SetCgroupAction::EnableResourceCaching() currently has a data race against all the
use fd_ functions like SetCgroupAction::ExecuteForProcess(uid_t uid, pid_t pid) etc.

ThreadA | ThreadB
-------------------------------------------------------------------------------------------------
in SetCgroupAction::EnableResourceCaching() | in SetCgroupAction::ExecuteForProcess(...)
-------------------------------------------------------------------------------------------------
| in SetCgroupAction::AddTidToCgroup(int tid, int fd)
-------------------------------------------------------------------------------------------------
fd_ = std::move(fd); /*modified fd_ value*/ |
-------------------------------------------------------------------------------------------------
| write(fd) /* crash here, fd is closed by ThreadA*/
-------------------------------------------------------------------------------------------------

So, add mutex lock to protect fd_ data race.

Bug: 134120826
Test: auto test, run the adb reboot test 100 times and no fdsan error report on libprocessgroup

Add libcgrouprc to ld.config.txt.

- In GSI, media.extractor has follow dependency.
media.extractor -> libmpeg2extractor (media ns) ->
libprocessgroup (media ns) -> libcgrouprc (default ns).
If libcgroupsrc can't link from libmpeg2extractor, media.extractor is crashed.

Test: media.extractor didn't die.

Link the "runtime" namespace to more namespaces.

The canonical location of the HWASAN runtime, an LL-NDK library, is being moved
to the runtime APEX. It is apparently the first LL-NDK library in the runtime
APEX that does not require a legacy symlink in /system/${LIB}. Therefore we
need to link the HWASAN runtime in the runtime namespace to various namespaces
so that the library can be loaded from outside of the namespace.

Also, add $SANITIZER_RUNTIME_LIBRARIES to
namespace.default.link.system.shared_libs. This is necessary because in
the accompanying Soong change, we cause the HWASAN runtime to be removed
from $LLNDK_LIBRARIES. In most cases, except for this one, this was a no-op
because we were already including both sets of libraries in shared_libs.
